Noise Cancelling Headphones Information

Active Noise Cancelling technologies (ANC) began to see widespread use in the 1950s to attenuate the noise experienced by pilots during helicopter and airplane flight. Since the earliest days of ANC, the technology has become a standard feature of consumer headphones with virtually every major manufacturer offering a model with integrated ANC technology.

Noise cancellation technology works by placing a microphone that detects background noise by measuring the amplitude of the noise wave. The microphone relays the information to a digital signal processor which emits a sound wave of the same amplitude with an inverted phase. When the contrasting sound waves meet, they effectively cancel each other out resulting in a significantly weakened noise wave.

This type of noise cancellation is particularly efficient at cancelling lower-frequency noise. To limit high-frequency noise from interfering with your music enjoyment, it is imperative to select noise-cancelling headphones with sufficient passive isolation. Passive noise cancellation is best achieved by closed back, circumaural (over-ear) headphones; nonetheless, there are plenty of in-ear and on-ear options that can provide significant passive noise cancellation to attenuate high frequency noise. Effective passive isolation in combination with ANC technology will offer the best results for listeners fixed on achieving the most focused and purely musical experience in virtually any environment.

Whether your demands require full-size headphones, compact on-ear headphones, or the ultra-portable in-ear monitor, our vast selection of noise-cancelling headphone models is sure to have an application for you. With models featuring rechargeable batteries as well as more traditional sources such as alkaline batteries, Sonic Electronix has you covered whatever your power source. Delivering selections from trusted and proven brands, we offer a blend of reliability, comfort, and service rare in on-line retail.
